Company Activities

Our Mission Our Core Activities

To be a leading single source

provider of premier measurement

and monitoring solutions for plant

maintenance and quality assurance.

Alignment Systems

Condition Monitoring

Nondestructive Testing

We make complex tasks easy to

achieve for our customers.


50% failures in rotating machinery are due to misalignment

Laser Alignment Systems

Systems and services for laser

alignment of rotating machinery.

Why alignment? Benefits of alignment

Misalignment increases

temperature, vibration and loads

Misalignment increases wear of

bearings, couplings, seals and

shafts

Downtime, production losses and

mechanical repairs generate high

operating and maintenance costs

Longer service life

Increased MTBF and uptime

Lower power consumption

Reduced temperature, vibration and

mechanical repairs

Lower operating costs

Higher product quality

Shaft alignment

Measurement of machine geometry

Bore alignment

Monitoring positional changes

Roll alignment with PARALIGN

Equipment Alignment for Prolonged Life


Agenda:

Short introduction to LCC

Costs over lifetime of a pump

Alignment of a motor pump systems

Relationship between alignment and costs of operation for a pump

Effects of misalignment

Possible savings – a few examples

Summary

Examples of alignment in chemical industry

Literature



LCC Life Cycle Costs

LCC includes following details:

LCC = Cic + Cin + Ce + Co + Cm + Cs + Cenv + Ccip + Cqu + Cd

Whereas Cic Original asset costs

Cin Costs for installation

Ce Costs for energy consumption

Co Costs for operation

Cm Costs for mainteance

Cs Costs for production downtime

Cenv Costs for environmental protection

Ccip Cleaning costs

Cqu Costs for quality improvments

Cd End of life costsQuelle: dena



32% cost for energy consumption 20% costs for maintenance

23% original asset costs

25% other costs for

operation

Power consumed

87%

Purchase cost

8%

LCC of a large water pump

At least 1/3, even up to 4/5, of the LCC are used up for

energy, depending on type of pump and application



Shafts are aligned, if the two shafts

are in line during operation conditions.



vertical angle vertical offset

horizontal angle horizontal offset



Intelligent condition based maintenance on rotating equipment is part of maintenance

strategies. This also includes precise alignment of shafts.

Analyzing the root causes of break down at rotating machinery it is found that over 50%

are due to misalignment.



• Results of misalignment

Increased abrasive wear of following parts:

Bearings

Seals

Couplings

Shafts

Reduction of MTBF – Mean Time Between Failure

Extreme: Noise due to increased vibrations

Increased power consumption



•Signs for a misaligned shaft system:

Strong radial and axial vibrations

Strong abrasion at bearings, sealings, couplings and broken shafts

(extreme)

Oil leakage at the bearings

High temperature at bearings and couplings

Loosing of bolting

Increasing energy consumption

And others more …



Example: Increase temperature at coupling and

• Lifetime of bearing

The smaller the offset of the two shafts at the coupling, the longer the

expected lifetime of the bearings.

• Lifetime of bearings

Maximal percentage of the expected lifetime of a bearing at the example

of a gearbox bearing, relative to a perfect aligned system.



• Repair of mechanical seals

The number of the repair of seals is reduced by 65% after consequent

and regular laser optical alignment has been introduced.

• Repair of mechanical seals

The lifetime of seals increases significantly with the precise alignment of

shafts.

• Repair of pumps

The number of pump repairs is droping 30% after the consequent and

regular introduction of laser optical alignment.

• Changes in terms of energy consumption

Significant savings concering the energy consumption can be achieved

due to precise shaft alignment

Perfect alignment reduces restoring forces and reduces the energy

consumption up to 10%

• Advantages of precis shaft alignment:

Optimizing the lifetime of assets

Cost reduction due to increased lifetime of wear parts (bearings, seals)

Reduction of longterm maintenance costs

Optimising reliability of the production process

Increase the availability of assest

Reduce the energy costs

Improve the safety in total

Contribution to a cleaner environment
